JAKARTA, Indonesia — A closed-door trial began Tuesday for the first of five janitors accused of raping a kindergartner in a bathroom at a prestigious international school in Indonesia’s capital that is facing a storm of controversy following more abuse allegations.

The custodians contracted to work at Jakarta International School were arrested in April and included five men and a woman. Police said one man committed suicide while in custody after drinking bathroom cleanser.

A media horde surrounded Agun Iskandar, 25, as he entered the courtroom. The remaining four suspects were expected to appear in court Wednesday, and they could face up to 15 years in jail if found guilty. The 6-year-old boy’s parents have sued the school, seeking $125 million in compensation.

All of the male defendants signed confessions, but one defense attorney, Mada Mardanus, argued they did so only because they were being tortured by police. He said the suspects deny the accusations.

Jakarta police spokesman Col. Rikwanto, who uses one name, strongly denied that any of the suspects were tortured during police questioning.

Mardanus also said the evidence was weak, with medical reports finding the boy had no major injuries or abnormalities even though the prosecutor’s indictment alleged he had been sodomized up to 13 times.

“We don’t want the court to punish the innocent simply because of public opinion, or just to please the public,” Mardanus said. “We hope the judge can see this case fairly, proportionately and humanely.”

The family’s lawyer, Andi M. Asrun, questioned the defense attorney’s claim. “How could they know the results of the medical reports, which are concealed and only for investigation purposes?” he said.

Since the case surfaced, two other families of young male students have come forward, and two school staff members have been detained without charges.

A campaign on social media has called for the release of Canadian school administrator Neil Bantleman and Indonesia teaching assistant Ferdinant Tjiong, who were arrested in July and are not part of this trial. Both have denied the allegations.

“We have zero doubt in the allegations against those teachers — that the allegations are false and they are innocent — and we are confident in the justice system that with time, they will be let free,” said Steve Druggan, deputy head of school for learning.

The school is attended by the children of foreign diplomats, businesspeople and Indonesia’s elite. It has 2,400 students aged 3 to 18 from about 60 different countries.

The school was also rocked earlier this year after an American who taught there for 10 years, William Vahey, killed himself as the FBI was investigating evidence that he sexually abused scores of teen boys while working at 10 schools across four continents.
